Small form-factor light engine reference design for desktop 3D printers using DLP® Pico™ technology


Design files


This 3D printing reference design enables faster development of desktop 3D printing applications using DLP® Pico technology. This design uses stereolithography (SLA) technique where a photo-resin is exposed to successive 2-dimensional patterns to create the 3-dimensional objects a single layer at a time. Due to layer-based printing, this technique is fundamentally much faster compared to alternate technologies. This reference design uses the DLP Pico 0.3-inch TRP HD 720p DMD (DLP3010) with the DLPC3478 display and light controller. The DLP3010 DMD offers a balance between resolution, size and cost, targeting small form-factor desktop 3D printers. Use cases include consumer, professional and industrial applications. This reference design includes an example light engine design that includes electronics and optics along with software to generate pattern sets to expose any kind of layer images used in the 3D printing process. The reference design also includes the DLPA2005 PMIC and LED driver.

  • 1280 × 720 resolution with flexible and precise light control 
  • Compact PCB layout supporting 720p (DLP3010) optical engine and including HDMI and USB connectivity 
  • Used in DLP3010EVM-LC layout 
  • 19-V input and LED current drive up to 2.5 A 
  • PC software GUI to send any types of patterns to the light engine
